did some datalogging last night, and i'm still learning some of this stuff

i'm starting out with a safe tune til we get everything sorted out, set up for 14 degrees total timing, was seeing about 13 with the 120 degree downstream temps

built motor, heads, cams, etc..., ported eaton 10lb lower and 75 shot

i guess i just always assumed that timing would start higher and as the rpms go up start dropping down

but my curve say in 1st is at 10 til about 4800 rpms, 12 til 5400 and then righ around shift time hits the 13

during 2nd gear it's about the same and such,

is the normal timing curve supposed to go up, don't know a ton about tuning but i would have thought it would start at say 18 or so and creap down as the rpms go up?

just tryin to learn more, can't wait til monday to talk to my tuner lol

my power curve looks really good on my dyno

 

That's pretty usual type of curve for a street tune, or a safe tune. Race tunes usually get locked so it holds the timing top to bottom. A lot of the slope is so you don't hit high load(reference for the timing tables) when going up a hill or something, but are not at WOT and have bad detonation.

 

That's not very much timing. Are you pushing a ton of boost or something?

 

it's seeing 16.5 on the 75 shot
